When geologists want to study an active earthquake fault, they often rely on a trenching study. ... They brace the walls, if needed, to prevent cave-ins, then they climb down into the trench and carefully map its walls, looking for signs of past earthquakes and ground movement.
Answer: D
Explanation: I just finished the exam :)
They have evolved to endure more as well as having been exposed to it from birth.
<span>first thing you need to do is find the area of the circle
A=(pi)r^2
You don't know r, but you do know the diameter is 10, and the diameter is twice the radius so r=5
Then plug that into the area formula, and you'll get A=25pi or 78.54 ft^2
If one bag covers 2 ft^2, then divide your area by 2 and round up to get the number of bags of concrete (40)

Headlands are known as high attacking waves, shores
that are rocky, forceful erosion and vertical sea cliffs. They are created when
the sea outbreaks on a coastline comprising of a group of hard and soft rocks. They
are surrounded by water.
<span>Bays on the other hand, are created when there is
less resistance of eroding soft rocks (e.g. sands and clays) forming a group of
stronger rocks (e.g. granite, chalk, limestone) into a headland. They are
surrounded by a land.</span>
